[Kamailio-Users] Transparent bridge mode

[Klaus Darilion]

Hi Vikram!

Why do you want to use multiple interfaces on server1 at all? As all 
servers have public IP I do not see the need for multiple interfaces. 
Why not make it simple and use:


Clients <------>Server1<------------>Server2
                 Kamailio+            Asterisk
                 rtpproxy
                 1 public IP          1 public IP

regards
klaus
